The Lowdown
Alright, this is Rusty. Let’s break it down.
First spot is Karramarro. Water temp is 73°, which is a solid 5° above the normal for this time of year. That’s notably warm, so you can go light on the rubber.
The first few days are a write-off. Saturday the 12th has pathetic 2ft WNW swell with a short 8-second period and barely any energy (59). The morning’s glassy but it’s not worth paddling out for. Sunday the 13th morning is the first real peek: 4ft NW groundswell, period up to 13 seconds, and combined energy at a moderate 543. Winds are flat calm – glass. That’s your first decent session, but it’s only the morning before the breeze gets cross-on. This is a point break, and it’s inconsistent – rarely breaks – so you’ve got to be on it. It’s also advanced only, and crowds are often when it’s working, so you won’t be alone.
There’s a dry stretch after Tuesday the 15th. The swell drops and onshores ruin things from Wednesday the 16th right through Friday the 18th. A few days of nothing.
Now for the real gem: Monday the 21st of September. Morning has 5ft NW groundswell, a very long 15-second period, combined energy at a strong 1090, and glassy winds. That’s the session to circle on the calendar. The long period will give the point long, lined-up walls. The afternoon jumps to 7ft and gets cross-on, so you want to be done by lunch.
Tuesday the 22nd morning is another good one: 5ft NW, 13-second period, 878 energy, and glassy winds. That’s a strong backup.
The end of the month has some clean cross-off days around the 24th with chest-high sets, but nothing touches that Monday the 21st.
To wrap it up: this spot is inconsistent, but when it fires, like Monday the 21st, it’s the real deal. It’s advanced-only and often crowded, so get there early.
Rusty.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Karramarro is 3 km (2 miles) from Zarautz. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Zarautz. Zarautz has rooms for a wide range of budgets as well as car hire and transport links.
